The Lowdown

Alright, this is Rusty. I gotta be straight with you – the next 16 days here at Kennebunk Beach are looking like a tough stretch for surf. We've got a long stretch of very little to get excited about. It's one of those periods where you might want to keep the board in the car but your expectations on the sand. The first real chance of anything rideable doesn't show up until late in the window.

Right now, and for most of the next week and a half, it's flat to tiny. The water temperature is running about 64°, which is a touch warmer than normal for this time of year, but that's about the only good news. The swell is tiny, mostly just a weak SE windswell with energy levels barely breaking into double digits. We're talking waves about 1 foot most days, with periods under 10 seconds. That's just not enough to push through, and the wind is mostly cross or cross-onshore, making it choppy. A little light rain Sunday the 13th adds some cloud cover but doesn't help the waves.

There are a couple of moments where it looks like it might clean up – like Sunday afternoon the 13th goes glassy, and Monday the 14th morning is clean with a light cross-offshore NNW wind, but even then the swell is only about 3 feet with a 6-second period (69 combined energy). That's barely enough for a fun little pop on a longboard, but not worth a dedicated trip.

The whole pattern is like this – a few cleaner windows with tiny swell, then more onshore chop. The waves just aren't tall enough or holding enough together.

Finally, late in the window, around Tuesday the 22nd, we see a slight pulse. The swell ticks up to about 4 feet from the E with a 7-second period and combined energy hitting 107. The wind on Tuesday morning looks clean and cross-off, which is a glimmer of hope. Then Wednesday the 23rd, we get a period in the afternoon with a 3-foot ESE swell, 9-second period, and a fresh breeze keeping it clean (169 combined energy). This is the most promising, but even then, it's just not a standout.

From the 24th and into the 25th, a bigger pulse of energy shows up on the charts – with combined energy reaching 278 on the 24th morning – but it's paired with a moderate cross-onshore wind, which will mess up the shape at this sheltered beach. The swell direction is mostly ESE to E, which is a bit awkward for the optimum ENE direction this spot likes.

So, what's the call? There are no true standouts. The best of a bad bunch is probably the Wednesday the 23rd afternoon, but even that is just "maybe okay." This stretch is a classic example of the area going quiet. It’s a blank run that’s more normal for this spot when the conditions line up wrong. Keep an eye on the sky, but don't hold your breath.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
